include integrated management system for existing bridges, thermal stress in mass concrete structures and earthquake englneenng. This study attempted to develop a decision support system for rehabilitation strategies of existing concrete bridges based on life cycle analysis. This proposed system is able to not only evqluaVe the serviceability of existing bridge members, but also offer some strategies based on a combinatign of maintenance cost minimization and quality maximization approach

By applying these algorithms to the optimization e approximation optimal solution (rehabilitation strategy) could be quickly found. problem, th Moreover, applications to some existing concrete bridges were presented so as to demonstrate the ridge management system. As a result, it was verified that this pTgposed suitability of proposed b system is able to estimate the deterioration ofbridge members and present various rehabilitation strategles.
